add_project · Todoist MCP: Risk & Policy

WHAT IT DOES

What add_project does on Todoist

AI agents use add_project to create or update resources in Todoist — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Todoist environment.

WHY IT NEEDS A POLICY

Why add_project needs a policy

This tool creates new projects in Todoist, which is a reversible write operation. The effect is limited to adding a new organizational container. It does not execute code, delete data, or move money. Severity is medium because creating unwanted projects clutters the user's workspace but can be easily undone by the user or a delete_project call.

From the tool's definition Tool name 'add_project' and sibling tools like 'create_task', 'add_comment', 'add_label', 'add_section' indicate data creation.

Verdict

add_project Rate-limited

add_project stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
